The SP PRO is just one part of a power system. The design of this system must be carefully considered
to ensure the SP PRO will perform as expected and to specification.
SP PRO Sinewave Interactive Inverter Chargers can be used in applications where no mains grid is
available, in mobile applications such as motor homes and boats and in grid support / grid feed systems.
Off Grid Stand Alone Power Systems (SPS)
The SP PRO is the heart of your power system. It quietly provides AC power from the battery bank and
renewable sources. The SP PRO can be programmed using SP LINK to monitor battery state of charge
and load conditions. The SP PRO will automatically start the generator only when required to charge the
batteries, supply loads heavier that the SP PRO can easily handle and efficiently utilise the generator to
supply the site load. These features will have the effect of increasing your battery life when configured
correctly.
The SP PRO can supply short-term overloads larger than its continuous load rating and will continue to
supply fault over-current for several seconds.
To minimize battery drain at very low load, the SP PRO can be configured to go into Power Save mode.
The SP PRO will automatically switch to and from Power Save mode when the unit senses sufficient AC
load.
The SP PRO can be configured to automatically start and stop the generator. When the generator is
running, the SP PRO will use the generator to power the site load; plus use any additional generator
capacity to charge the batteries. If the site loads are greater than the generators output, then the SP PRO
will add its power to the generator. When the site loads are reduced, the SP PRO will return to battery
charging. The above operation will happen automatically, whilst always maintaining “no break” power to
the site.
